Description

Technical Field

[0001] This utility model relates to the field of charging docks, and in particular to a protective structure for the follow-up rotation opening and closing inside the charging port and a charging dock using the same. Background Technology

[0002] Charging docks are widely used in the new energy industry, such as charging docks for new energy vehicles or charging piles. These charging docks are high-voltage, high-current components. When the charging dock is not in use, its charging port needs to be sealed to prevent electric shock. Currently, an external protective cover is installed on the charging interface end. The cover is opened when charging. The drawback is that when the cover is open, before the charging gun is inserted into the charging dock, the power terminal is exposed to the field of vision, which poses a risk of electric shock due to misoperation or contact between metal tools and the power terminal. Utility Model Content

[0003] To address one or more of the aforementioned problems, this utility model provides a follow-up rotating opening and closing protective structure inside the charging port and a charging base using the same.

[0004] According to one aspect of the present invention, the following charging port rotational opening and closing protective structure includes: a panel, two arc springs, two inner protective covers, and a follower block;

[0005] The panel is installed at the front end of the charging base body, above the charging port of the panel. The rear end face of the panel is symmetrically provided with two vertical fixing shafts and two first arc grooves, and the first arc grooves and fixing shafts on the same side are concentrically arranged.

[0006] Two arc-shaped springs are placed in two first arc grooves, with their upper ends connected to the upper end of the rear end of the panel and their lower ends connected to the lower end of the inner protective cover.

[0007] Two transversely symmetrical inner protective covers are rotatably connected to two fixed shafts, and the pull holes at the upper ends of the two inner protective covers are transversely slidably connected to the two pull shafts of the follower block;

[0008] The follower block is vertically slidably connected to the upper rear side of the panel, and the lower front side of the follower block is provided with an inclined contact surface, which enters the upper part of the charging port.

[0009] When not charging, the two inner protective covers are located directly in front of the power terminals for protection. When charging, the charging gun contacts the contact surface, causing the follower block to move upward, which drives the inner protective covers to rotate and expose the power terminals. The lower end rotates in the first arc groove to compress the arc spring. When the charging gun disengages from the contact surface, under the action of the arc spring, the lower end rotates in the opposite direction in the first arc groove, causing the inner protective covers to reset.

[0010] The beneficial effects of this rotating and opening protective structure inside the charging port are as follows: First, the protective structure is installed inside the charging port. When the charging gun is not yet inserted into the charging socket, the power terminals are covered by the built-in inner protective cover and are not exposed. When the charging gun enters the insertion port, the inner protective cover gradually opens until the charging gun's insertion terminals are reached. Therefore, the power terminals are not exposed during the entire insertion and removal process, thus avoiding the risk of electric shock caused by misoperation or contact between metal tools and the power terminals, resulting in high safety performance. Second, the inner protective cover of this protective structure passively opens as the charging gun is inserted. Furthermore, it automatically resets for protection when the charging gun is removed, without any unnecessary drive or power components or corresponding control parts, resulting in a simple overall structure that is easy to operate. Thirdly, the structure uses an arc-shaped spring, which compresses as the inner protective cover rotates outward and elastically resets as the inner protective cover rotates inward, resulting in smoother overall movement, higher stability and reliability. At the same time, this structure further simplifies the product size, making the overall structure compact. Fourthly, the arc-shaped spring is confined in the first arc groove and its two ends are limited by the upper and lower connecting ends, making its running trajectory controllable and free from abnormal jumping or swaying.

[0011] In some embodiments, a fixed shaft is rotatably connected to the vertical first shaft hole on the inner side of the upper end of the inner protective cover;

[0012] The pull hole is a horizontal elongated hole or a waist-shaped groove in the middle of the upper end of the inner protective cover.

[0013] In some embodiments, the outer side of the upper end of the front side of the inner protective cover is also provided with a second arc groove concentric with the first shaft hole. The two arc grooves are arranged one after the other and rotate relative to each other. The upper end enters the upper end of the second arc groove and the lower end enters the lower end of the first arc groove. The outer end of the arc spring is located in the first arc groove and the inner end is located in the second arc groove.

[0014] In some embodiments, the upper end is formed by an integral, rearwardly vertically protruding upper wall of the first arc groove, and the lower end is formed by an integral, forwardly vertically protruding lower wall of the second arc groove.

[0015] In some embodiments, the first and second arc grooves are semicircles with the same cross-section, and the two are sealed together to form an arc cavity; the upper and lower ends are semicircular protrusions.

[0016] In some embodiments, the follower block includes a rear crossbeam and two lifting guide arms that are symmetrically and vertically connected to the front side of the rear crossbeam. The rear crossbeam is located behind two inner protective covers, and two pull shafts that are symmetrically connected to two pull holes at both ends of its front side are slidably connected.

[0017] The lifting guide arm is located between two inner protective covers and protrudes from the sliding connection panel. The lower front side of the lifting guide arm has a rearwardly inclined contact surface.

[0018] In some embodiments, above the charging port, two vertical sliding grooves and a lower baffle extending vertically backward are symmetrically arranged in the middle of the rear end face of the panel. The lower baffle is located in the middle of the lower end of the two vertical sliding grooves, and the two vertical sliding grooves are located inside the two fixed shafts. The vertical sliding grooves are slidably engaged in the lifting guide arm.

[0019] In some embodiments, a rear positioning plate is also included, and the space enclosed by the rear positioning plate and the panel is the movable area of ​​the inner protective cover; a plurality of screw hole blocks are provided on the rear side of the panel, a plurality of receiving grooves are provided on the outer edge of the rear positioning plate, a rear protrusion with a first through hole is formed on the rear side of the receiving groove, the receiving groove is sleeved on the screw hole block, the threaded part passes through the first through hole and is screwed into the screw hole block to fix the rear positioning plate behind the panel, and the rear protrusion enters the front mounting groove of the charging base body.

[0020] In some implementations, an openable outer protective cover mounted on the front of the panel is also included, which can either close the front of the charging port or open to expose the charging port, thus providing primary protection.

[0021] According to another aspect of this utility model, the charging dock includes: a charging dock body and a follow-up rotating opening and closing protective structure connected to the front of the charging dock body, which is any one of the above-mentioned structures. The advantages of this charging dock are: no risk of electric shock and high safety performance. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0033] Figures 1 to 8 The illustration schematically shows a charging port follow-up rotation opening and closing protective structure and a charging base using the same, according to one embodiment of the present invention.

[0034] like Figures 1 to 7 As shown, the following is a protective structure for the internal rotation and opening of a charging port: a panel 1, two arc springs 2, two inner protective covers 3, and a follower block 4.

[0035] Panel 1 is installed at the front end of the charging dock body 01. The charging port 10 in the middle of panel 1 is directly opposite the terminal of the charging dock body 01. Above the charging port 10 of panel 1, two vertical fixing shafts 11 and two first arc grooves 12 are symmetrically arranged on the rear end face of panel 1. The first arc grooves 12 and fixing shafts 11 on the same side are concentrically arranged.

[0036] Two arc-shaped springs 2 are placed in two first arc grooves 12, with their upper ends connected to the upper end 13 at the rear end of the panel 1 and their lower ends connected to the lower end 30 of the inner protective cover 3.

[0037] Two horizontally symmetrical inner protective covers 3 are rotatably connected to two fixed shafts 11, and the pull holes 31 at the upper end of the two inner protective covers 3 are horizontally slidably connected to the two pull shafts 43 of the follower block 4; the two inner protective covers 3 can rotate to close the two sides of the charging port 10 and protect the power terminal 011 at the rear.

[0038] The follower block 4 is vertically slidably connected to the upper rear side of the panel 1, and the lower front side of the follower block 4 is provided with an inclined contact surface 40, which enters the upper part of the charging socket 10.

[0039] When not charging, the two inner protective covers 3 are located directly in front of the power terminal 011 for protection. When charging, the charging gun enters the charging port 10 and contacts the contact surface 40, causing the follower block 4 to move upward, which drives the inner protective cover 3 to rotate and expose the power terminal 011. The lower connection end 30 rotates in the first arc groove 12 to compress the arc spring 2. When the charging gun is pulled out and disengaged from the contact surface 40, under the extension of the arc spring 2, the lower connection end 30 rotates in the opposite direction in the first arc groove 12, and the follower block 4 moves downward to reset, which drives the two inner protective covers 3 to rotate inward and return to their original positions directly in front of the power terminal 011, so that the follower block 4 and the inner protective cover 3 are reset.

[0040] The beneficial effects of this rotating and opening protective structure inside the charging port are as follows: First, the protective structure is installed inside the charging socket 10. When the charging gun is not yet inserted into the charging base, the power terminal is covered by the built-in inner protective cover 3 and is not exposed. When the charging gun enters the socket 10, the inner protective cover gradually opens until the charging gun inserts into the terminal. Therefore, the power terminal 011 will not be exposed during the entire insertion and removal process, thus avoiding the risk of electric shock caused by misoperation or contact between metal tools and the power terminal, resulting in high safety performance. Second, the inner protective cover 3 of this protective structure opens passively as the charging gun is inserted. Furthermore, it automatically resets for protection when the charging gun is removed, without any unnecessary drive or power components or corresponding control parts, thus making the overall structure simple and easy to operate; thirdly, the structure adopts an arc-shaped spring 2 structure, which is compressed as the inner protective cover 3 rotates outward and elastically resets as the inner protective cover 3 rotates inward, making the overall action smoother, more stable and reliable. At the same time, this structure further simplifies the product size, making the overall structure compact; fourthly, the arc-shaped spring 2 is confined in the first arc groove 12 and its two ends are limited by the upper end 13 and the lower end 30, so its running trajectory is controllable and there is no abnormal jumping or swaying phenomenon.

[0041] Furthermore, two fixed shafts 11 are integrally and vertically connected to the rear end face of the panel 1. The two fixed shafts 11 are located above the charging port 10 and are symmetrical about the vertical center line of the charging port 10.

[0042] The vertical first shaft hole 32 on the inner side of the upper end of the inner protective cover 3 is rotatably connected to the fixed shaft 11;

[0043] The pull hole 31 is a transverse elongated hole or waist-shaped groove in the middle of the upper end of the inner protective cover 3. The pull hole 31 and the cylindrical pull shaft 43 are fitted together with a small gap or fitted together vertically. Its beneficial effect is that this setting can achieve good power input and stable operation without jamming.

[0044] Furthermore, the upper outer side of the front side of the inner protective cover 3 is also provided with a second arc groove 33 concentric with the first shaft hole 32. The second arc groove 33 and the first arc groove 12 are arranged one after the other and rotate relative to each other. The upper end 13 enters the upper end of the second arc groove 33 and the lower end 30 enters the lower end of the first arc groove 12. The outer end of the arc spring 2 is located in the first arc groove 12 and the inner end is located in the second arc groove 33, and its two ends are respectively connected to the upper end 13 and the lower end 30. Preferably, the upper end 13 is a rear protrusion formed by the vertically protruding rearward integrally from the upper wall of the first arc groove 12, and the lower end 30 is a front protrusion formed by the vertically protruding forward integrally from the lower wall of the second arc groove 33. Preferably, the first arc groove 12 and the second arc groove 33 are semicircles with the same cross section, and the two are sealed and fitted together to form an arc cavity for placing the arc spring 2; the upper end 13 and the lower end 30 are semicircular protrusions, and the semicircular protrusions and the semicircular cross sections of the arc grooves are the same or set with a small gap. Its beneficial effects are: the arc spring 2 is installed and fixed with high precision, making the movement more stable and reliable.

[0045] Furthermore, the upper and lower ends of the arc base plate of the inner protective cover 3 are inclined surfaces and the outer side is provided with several clearance notches, and the space surrounded by the upper ends of the two arc base plates is the contact space.

[0046] Four power terminals 011 are symmetrically distributed on both sides of the lower end of the front shell of the charging base body 01. In its natural state, the lower end of the arc-shaped substrate is directly opposite the four power terminals 011. The beneficial effect of this arrangement is that it achieves a good secondary shielding effect.

[0047] Furthermore, the follower block 4 includes a rear crossbeam 41 and two lifting guide arms 42 that are symmetrically connected vertically to the front side of the rear crossbeam 41. The rear crossbeam 41 is located behind the two inner protective covers 3, and two pull shafts 43 that are symmetrically connected to the two pull holes 31 at both ends of its front side are slidably connected.

[0048] The lifting guide arm 42 is located between the two inner protective covers 3 and protrudes from the sliding connection panel 1. The lower front side of the lifting guide arm 42 is provided with a rearwardly inclined contact surface 40. Its beneficial effect is that this setting can improve the accuracy of the follower block 4's movement and ensure the accuracy of power input.

[0049] Furthermore, above the charging port 10, two vertical sliding grooves 14 and a lower baffle 15 extending vertically to the rear are symmetrically arranged in the middle of the rear end face of the panel 1. The lower baffle 15 is located in the middle of the lower end of the two vertical sliding grooves 14, and the two vertical sliding grooves 14 are located inside the two fixed shafts 11. The vertical sliding grooves 14 are slidably fitted into the lifting guide arm 42 without gaps.

[0050] The rear crossbeam 41 and the lifting guide arm 42 are rectangular prisms, and the vertical slide 14 is a rectangular groove. The beneficial effect of this design is that it improves positional accuracy and prevents abnormal movements.

[0051] Furthermore, it also includes a rear positioning plate 6 threadedly connected to the rear side of the panel 1. The enclosing space between the rear positioning plate 6 and the panel 1 is the moving area of ​​the inner protective cover 3. One side of the inner protective cover 3 is attached to the rear of the panel 1, and the other side is attached to the front of the rear positioning plate 6 or connected to the front of the rear positioning plate 6 with a small gap. The rear positioning plate 6 has a central through hole 61 with the same outline size as the charging port 10. The upper edge of the central through hole 61 has a relief opening 62 that cooperates with the lower baffle 15. Guide protrusions 63 are provided on both sides of the relief opening 62. The guide protrusions 63 are attached to the rear surface of the lifting guide arm 42. Its beneficial effect is that this setting ensures that the components do not wobble back and forth during operation.

[0052] Preferably, the rear side of the panel 1 is provided with multiple screw hole blocks 16, and the outer edge of the rear positioning plate 6 is provided with multiple receiving grooves 64. The rear side of the receiving grooves 64 forms a rear protrusion 66 with a first through hole 65. The receiving grooves 64 are fitted onto the screw hole blocks 16, and the threaded part 5 passes through the first through hole 65 and is screwed into the screw hole block 16 to fix the rear positioning plate 6 to the rear of the panel 1. When the panel 1 is installed on the charging base body 01, the rear protrusion 66 enters the mounting groove 012 of the front end shell of the charging base body 01. Its advantages are: the connection strength is high and the size is compact.

[0053] The rear positioning plate 6 has multiple process through holes 67 in the middle. The advantages of this design are that it facilitates the arrangement of other components and reduces the overall weight.

[0054] Furthermore, it also includes an outer protective cover, which can be opened and installed on the front of the panel 1. It can close the front side of the charging port 10 or open to expose the charging port 10, thus achieving primary protection.

[0055] The outer protective cover is rotatably hinged to one side of panel 1 or slidably connected to panel 1; when not charging, the outer protective cover closes the front of the charging port 10; when charging, the outer protective cover opens to expose the terminals of the charging base body 01 behind the charging port 10. Its beneficial effect is: double protection, higher safety performance.

[0056] like Figure 8 As shown, the charging dock includes: a charging dock body 01 and a follow-up rotating opening and closing protective structure 00 connected to the front end of the charging dock body 01, which is one of the aforementioned types. The advantages of this charging dock are: no risk of electric shock and high safety performance.

[0057] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
